'MbedI2C' does not name a type #39

In Acceleration detection sketch wrt MPU6050 sketch 27.1

at line 10 

MbedI2C iic(6,7);

Get compilation error 'MbedI2C' does not name a type

Seems another library needs to be referenced.

Found a solution:

//MbedI2C iic(6,7);
TwoWire iic(i2c1,6,7);  
//TwoWire iic(i2c0,4,5);

TwoWire is instatiated as in wire,h

TwoWire(i2c_inst_t *i2c, pin_size_t sda, pin_size_t scl);

i2c_inst_t is a struct in ic2.h that contains the following specific instance references:

In i2c.h:


typedef struct i2c_inst i2c_inst_t;

...
...

extern i2c_inst_t i2c0_inst;
extern i2c_inst_t i2c1_inst;

#define i2c0 (&i2c0_inst) ///< Identifier for I2C HW Block 0
#define i2c1 (&i2c1_inst) ///< Identifier for I2C HW Block 1
```.

Hi! It seemed that you are using the Raspberry Pi Pico kit, and not using the latest code. You can download the latest one with this link: https://github.com/Freenove/Freenove_Ultimate_Starter_Kit_for_Raspberry_Pi_Pico/archive/refs/heads/master.zip
